摘　　要：针对广东某地区加油站扩建L-CNG加气功能的案例,从工作原理、结构组成、建造组装流程等方面介绍了加油加气站内CNG储气的两种形式:储气井和储气瓶组。从安全性、占地面积、检验检测、使用寿命、施工难度、建造成本、可移动性等方面对比分析了两种储气形式的优缺点:储气井安全性高、占地面积小;储气瓶组施工难度小,建设周期短,便于移动。因而,在加油站内扩建L-CNG功能推荐选用储气井储气,同时指出了应用储气井储气的几点注意事项。With a case study of expanding L-CNG filling facilities in a filling station in Guangdong, this paper presents the CNG storage in filling stations in two forms, i.e. storage well and cylinder group, in aspect of operating principle, structural composition, and construction/assembling flow. Through comparative analysis on both storage forms in terms of safety, floor space, verification and detection, service life, construction difficulty, construction cost and removability, this paper reveals that the CNG storage well is more safe, with small floor space, whereas the CNG cylinder group can be easily constructed in a shorter period and it is also removable. Therefore, storage well is recommended when the L-CNG facilities are expanded in a filling station. Additionally, this paper points out some considerations for L-CNG storage well.
